Abstract:
A table is presented by means of which changes in arch length and arch circumference can be more accurately predicted, thereby simplifying treatment planning for cases with special problems, e.g. a Bolton discrepancy. A fundamental condition for the use of this table is that the anterior arch from canine to canine forms a parabolic curve.
